I Was Exercising Last Tuesday And Twisted My Ankle Laterally

I was exercising last Tuesday and twisted my ankle laterally while walking. I have elevated it daily as much as I can and iced it the first 3 days and used compression until today. I do not have bruising to my ankle but there is swelling about 1 inch diameter completely around lateral side of ankle bone. I notice swelling slightly decreased first thing in am upon rising, but this is when my ankle also hurts the most. As the day progresses the pain decreases and the swelling increases and gives me a feeling of greater mobility with decreased pain. is this normal healing for a sprained ankle or do I need to go have it looked at. thanks, michelle
